The Gridiron II is similar to its older brother, but refined with a large number of smaller pins. The smaller pins work well at getting grip on hard packed tracks with a layer of dust that sits on top. The Gridiron II also makes a great front tire choice to smooth out steering on 2wd SC trucks. Available with red inserts or pre-mounted pairs on Cyclone wheels in our race proven Super Soft, and Soft compounds.As always, designed and proudly made in the USA.
